Dilute solutions have more osmotic potentials due to

Options

A. More number solute molecules
B. More number of solvent molecules and less number of solute particles
C. More reduction in the capacity of water to do work
D. More decrease in the free energy of water molecules

Answer

To answer the question "Dilute solutions have more osmotic potentials due to," we will analyze the options provided and determine the correct answer step by step.

### Step 1: Understand Osmotic Potential
Osmotic potential (also known as osmotic pressure) is a measure of the tendency of water to move into a solution due to solute concentration. It is influenced by the number of solute particles in a solution.

### Step 2: Define Dilute Solutions
Dilute solutions are those that have a relatively low concentration of solute compared to solvent. This means there are more solvent molecules than solute molecules.

### Step 3: Analyze the Options
1. **More number of solute molecules**: This is incorrect because a dilute solution has fewer solute molecules.
2. **More number of solvent molecules and less number of solute particles**: This is correct. In a dilute solution, the presence of more solvent molecules contributes to a higher osmotic potential.
3. **More reduction in capacity of water to do work**: This is misleading. Osmotic potential is not directly related to the capacity of water to do work in this context.
4. **More decrease in free energy of water molecules**: While free energy is a factor in osmotic potential, this option does not accurately describe why dilute solutions have higher osmotic potentials.

### Step 4: Conclusion
Based on the analysis, the correct answer is:
**Option 2: More number of solvent molecules and less number of solute particles.**
